If you breed with a boar who has piri piri you are far more likely to produce piglets with them which is definitely preferable to piglets without them.
it is rare for anyone to keep a boar who doesn't have them as he wouldn't really be good enough to use for breeding.
i'd advise you to go for the best you can get

Thank you for the advice. It was really only because she didn't have them, but taking into account what you have said I will just search for the best boar I can find; so if anyone can help please let me know.

I'm not sure where Baddington is but it takes us an hour and a half from where we are near York to my sisters in Altrincham,Cheshire, perhaps a bit far for you?
I have a proven tri-coloured boar with piris called Henry, you can see a picture of him on www.oakhousekunekune.co.uk, he is very gentle and friendly and has sired many litters.
